This original pair was contributed as a "verb phrase" match, not sentences. We still have a number of these left over from the Tanaka Corpus import.

Keep early hours.
早寝早起きをする。

In my opinion, both of these should be deleted, and maybe the translations, too.
However, both of these could be considered sentences, though they don't match as sentences.
The English, though possibly an imperative sentence, is very unlikely as such.
